通过结构面的数学建模，使采集所得结构面数据的处理实现了信息化，程序化，应用多功能数据库在计算机上人机交互划分岩体结构，初步实现岩体结构的信息化，并且通过结构面与相关实体的真三维实体模型的建立，既可清晰直观的展示结构面模型的空间形象，又可容易的切割模型并获取切图的数据，对不稳定块体的分析研究提供了强有力的辅助手段。

According to various of the technical difficulties such as low drilling efficiency in hard rock and short service life of diamond drilling bit, analysis was made on the inherent links between blade-extruding of hot-pressing diamond and rock abrasiveness.

中文摘要：针对在坚硬致密岩石中钻进时效低和钻头使用寿命短的技术难题，分析了热压钻头的金刚石出刃与岩石研磨性等岩性之间的内在联系，认为钻头的胎体成分及其性能是关键，硬而带脆性的胎体性能有利于金刚石出刃，从而能提高钻进速度。

The results suggested that all ore rock samples have potential to generate acid. So effective measures are expected to be taken to prevent acid rock drainage generating.

研究结果表明，所有的矿石样品都具有产酸潜力，需要对矿石进行有效的防控，以阻止酸性岩排水的产生。

We now look at this rock is red, of course, not the blood of the ancient craftsmen, because Tiger is the acid rock rhyolite, its original stone is red.

我们现在看这块石头是红颜色的，当然不是古代工匠的鲜血，因为虎丘的岩质是酸性流纹岩，它的石质原本就是红色的。

Many data and discussions about carbonate rock dissolution in CO2 solution have been published. In this paper, special simulation experiments were carried out in order to understand the dissolution behaviors of carbonate rocks in organic acid and H2S solution. The results show that, as the temperature rises from 20℃ to 200℃, the dissolution rate of carbonate rock in organic acid increases with temperature below 90℃ and decreases above 90℃.

CO2对碳酸盐岩储层的溶蚀作用已有不少学者进行了研究，本文则以一个全新的模拟实验方式对不同类型碳酸盐岩在有机酸和H2S水溶液中的相对溶蚀能力进行了研究，结果发现随温度从常温升高至200℃，有机酸对碳酸盐岩的溶蚀能力由弱变强再变弱，在90℃左右溶蚀能力最强。
